We invite you to help sustain the Museum by becoming a member. Annual memberships are on the basis of the calendar year; you may join at any time. For the 2021 membership year, NML will retain the 2020 rates. As before, all members receive access to the Transparent Language Online language learning software, recognition as a Builder of the Museum, notification of opportunities and events as well as a monthly newsletter.

We rely on membership dues as the principal means of financial support, so recruitment of new members is of vital importance to us. So sound out your friends and colleagues, recruit your relatives; give memberships as a birthday or holiday gift. At the holiday time, you can give your favorite teacher a membership. We also welcome your tax-deductible donations as an additional means of supporting the Museum. Use the Donate button above to pay online with secure PayPal payments (you do not have to have a PayPal account to pay with a credit card online).
